.NITED STATES GEORGE V. GOODELL, OF BEARDSTOWN, ILLINOIS HOISTING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 242,629, dated June 7, 1881.

Application filed February 24, 1881.

To all whom it may concern Be it known that I, GEORGE W..Goo1)nLL, of Beardstown, in the county of Cass and State of Illinois, have invented a certain new and' useful Improvement in Hoisting-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My improvement relates to a hoisting apparatus, being specially adapted in some of its features for raising ice in the process of housing it; and my improvement consists in the device hereinafter described and claimed.

In the drawings, Figure 1 is an elevation of my improvement, showing the cage or hoisting-frame, part in transverse section and part in end view. Fig. 2 is an end view of the driving mechanism, showing the means for changing the power and the strap-brake by which the cage is held at any desired height. Fig. 3 is a top view of the driving mechanism and the tilting-block, showing the tilting-lever broken away. Fig. 4 is a longitudinal section of the cage, showing part of the wall of an ice-house. Fig. 5 is an enlarged detail section of the adjustable block for tilting the cage to unload the ice.

A A are guide-posts between which the cage A works, and B B are the guide-posts between which the counter-balance B works. The cage has friction-rollers a, and the counter-balance friction-rollers 1), working against their posts A and B respectively.

G is a horizontal timber supported on the posts A and B, and on which the block D and cable-pulleys D, D and D have bearing, as shown in Fig. 1.

The cable E is made fast at one end to the block D, from which it passes down and beneath the counter-balance pulley B thence up over the pulleys D, thence down to the drum F, around which itis coiled-say five or six timesto prevent its slipping; from thence up over pulleys D thence down beneath cage-pulley A thence up over pulleys D and from thence down to the attachment to on the cage-post A.

The counter balance B may be a heavy weight of any kind, but I prefer to make it in the shape of a box, to be filled with stones or (No model.)

other heavy matter, so that its weight may be Varied at will.

The cage A has vertical side pieces, a crossbar a, and horizontal base-piece a. a are braces.

G is the ice-frame, which is pivoted at g to the base-piece a of the cage so thatit may be tilted to cause the ice to slide oft it when its inner end comes in contact with the adjustable block K.

H is a yoke secured to the inner end of the frame G. There may be two of these yokes, one secured to each side of the inner end of the frame, its purpose being to tilt the ice slide or frame G by coming against the adjustable block or cross-piece K. By this arrangement the cross-piece K does not interfere with the ice moving on the slide, as it would do were the end ofthe frame to come in direct contact with it.

The frame Gr has its pivoted connection on the base-piece a, a little nearer its inner than its outer end, so that until the inner end comes in contact with the tilting-block K the frame will naturally incline outward, so that the ice will not slide off the frame inward before the proper time.

'i are removable blocks, (see Fig. 4,) held in place upon the inner end of the base-piece a by staples or yokes I. As stated, the blocks are removable, so that one or more of them may be removed to allow any desirable amount of tilting movement to be given to the iceframe Gr.

To the outer end of the frame G is pivoted a lever, J, (see Fig. 4,) connected by its lower end by means of a cord, rope, or chain to the base-piece a of the cage, as shown. The purpose of this lever is to start the ice to sliding when that end of the frame G is raised by the lowering of the other.

The adjustable tilting-block K,which reaches across the window-way or doorway of the house, consists of a block of wood having bolts k, whose outer ends, when in their outer position, rest in holes k in the uprights k secured to the side of the building, each side of the doorway. The bolts k are capable of endwise movement in the block K, and are attached by rods or links k to the vertical bar 7c,workin g in a central hole in the block. The bar It has a ring or handle, is", at its upper end, by which it is raised to cause the ends of the bolts k to retreat into the block. This vertical bar k acts as a means for forcing the bolts koutward and also as a guide.

The adjustable block K is raised and lowered by means of cords or ropes L secured to its ends, as shown in Figs. stand 5, and which pass over pulleys l and down to any suitable point within handy reach. When the block is to be raised or lowered the vertical bar k is raised, either directly by hand or by a cord passing up over a pulley and down within handy reach of the operator,which retracts the bolts. The block is then raised by means of the cords or ropes L until it reaches the proper point, when the vertical bar is released and the ends of the bolts kprotrude into the holes in the uprights.

Upon the shaftf of the drum F, one end of which has bearing in one of the guide-posts B, and the other end of which has bearing in the upright f, is a friction-wheel, M, and beneath this are two friction-wheels, N 0, turning in opposite directions. The wheels N O are supported in a bearing-block, 1 pivOted by means of an adj usting-bolt, Q, to the bridge it, which is secured to a fixed object. By this pivoted connection either of the wheels N 0 may be brought in contact with the wheel M to cause it to rotate in either direction. The wheel N may turn in the direction shown by the arrow, and would, when brought in contact with the wheel M, raise the elevator-cage and depress the counter-piece. The wheelsN 0 are connected together either by simple cogwhcels n 0 on their shafts n 0, as shown in Fig. 3, or they may be connected by frictionwheels in contact one with the other. The wheel 0 will thus turn in the opposite direction to that of wheel N, so that when it is brought in contact with wheel M the cage will descend and the counter-balance ascend. The wheel Nreceives motion from its shaft n, which may be turned continuously by a steam-engine or other motor, and the shaft a may extend to a number of similar hoisting-machines in line, so that they may all be driven by the same motor. The bearing-block P is tilted on its pivot to bring either of the friction-wheels N 0 into contact with the wheel M by a lever, 1 and any suitable device may be added to hold the lever in any position placed. The block P is made vertically adjustable by two nuts, q, on the bolt Q, so that as the frictionwheels become worn away they may be raised.

S is a strap-brake, which is made fast at one end to the block T, and which extends up over the wheel M and down to a lever, U, to which the other end is made fast, and which has pivoted bearing on the block V. By this brake the rotation of the wheel M is checked, and consequently the cage and counter-balance stopped at any time desired. The brake-lever may be held up by a spring or otherwise, so that the brake will not have constant bearing on the wheel M.

Wis a block or stop, against which the inner end of the ice-frame G comes to hold that end up while being loaded.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The independent adjustable tilting-block K, having horizontal bolts k, in combination with the uprights k having holes la, as set forth.

2. The tilting-block K, having bolts k,coupling-links k, and vertical rod k, in combination with uprights it, having holes k, the said block being adjustable independently of and adapted to limit the upward movement of the platform, as set forth.

3. The combination of cage A, cable E, drn m F, pulleys D D D-', driving frictionwheel M, driving-wheels N 0 on pivoted block I, and counter-balance B, substantially as set forth, all in combination with guide-posts A and B.

4. The combination of cage'A, cable E, drum F, pulleys D 1) D driving friction-wheel M, driving-wheels N O on adjustable block P, adjusting-bolt Q, bridge B, and guide-posts A B, all made substantially as and for the purpose set forth.

5. In combination with guide-posts A B, cage A, cable E, drum F, pulleys D D D, drivingwheel M, wheels N O, pivoted block P, and counter-balance B, the brake S, by which the cage is held at any desired elevation.
